Description The isolation of Planococcus glaciei (designed strain CNCTC 7660) from blood of a patient with appendicitis is reported. Species P. glaciei (type strain CGMCC 1.6846( T)) was for the first time identified as an environmental bacterium acquired from a glacier in China in 2009. To reveal the identity of the isolate CNCTC 7660, the 16S rDNA sequencing and the whole genome sequencing (Illumina MiSeq, Oxford Nanopore) were performed. The level of 16S rDNA gene sequencing similarity between CNCTC 7660 and CGMCC 1.6846( T) was 99.55%. Phylogenetic analysis and average nucleotide analysis (ANI) based on the whole genome sequencing confirmed that the isolate CNCTC 7660 and CGMCC1.6846( T) had ANI value above the taxonomic threshold for belonging to the same species (95%). The G + C content of CNCTC 7660 DNA was 46.8% (mol/mol). Except for the growth temperature, strains CGMCC1.6846( T) and CNCTC 7660 were distinguished also biochemically. Due to the lack of information about the pathogenicity of P. glaciei, the possibility that it exerts pathogenicity in persons is suggested. But for understanding the nature of this species, further cases are needed.
